FLEX 6000 Programmable Logic Device Family Data Sheet
General
Description
The Altera
®
FLEX 6000 programmable logic device (PLD) family provides
a low-cost alternative to high-volume gate array designs. FLEX 6000
devices are based on the OptiFLEX architecture, which minimizes die size
while maintaining high performance and routability. The devices have
reconfigurable SRAM elements, which give designers the flexibility to
quickly change their designs during prototyping and design testing.
Designers can also change functionality during operation via in-circuit
reconfiguration.
FLEX 6000 devices are reprogrammable, and they are 100% tested prior to
shipment. As a result, designers are not required to generate test vectors
for fault coverage purposes, allowing them to focus on simulation and
design verification. In addition, the designer does not need to manage
inventories of different gate array designs. FLEX 6000 devices are
configured on the board for the specific functionality required.
Table 3
shows FLEX 6000 performance for some common designs. All
performance values shown were obtained using Synopsys DesignWare or
LPM functions. Special design techniques are not required to implement
the applications; the designer simply infers or instantiates a function in a
Verilog HDL, VHDL, Altera Hardware Description Language (AHDL), or
schematic design file.

The applications in this table were created using Altera MegaCore
TM
functions
.
FLEX 6000 devices are supported by Altera development systems; a
single, integrated package that offers schematic, text (including AHDL),
and waveform design entry, compilation and logic synthesis, full
simulation and worst-case timing analysis, and device configuration. The
Altera software provides EDIF 2 0 0 and 3 0 0, LPM, VHDL, Verilog HDL,
and other interfaces for additional design entry and simulation support
from other industry-standard PC- and UNIX workstation-based EDA
tools.
The Altera software works easily with common gate array EDA tools for
synthesis and simulation. For example, the Altera software can generate
Verilog HDL files for simulation with tools such as Cadence Verilog-XL.
Additionally, the Altera software contains EDA libraries that use device-
specific features such as carry chains which are used for fast counter and
arithmetic functions. For instance, the Synopsys Design Compiler library
supplied with the Altera development systems include DesignWare
functions that are optimized for the FLEX 6000 architecture.
The Altera development system runs on Windows-based PCs, Sun
SPARCstations, and HP 9000 Series 700/800.

Functional
Description
The FLEX 6000 OptiFLEX architecture consists of logic elements (LEs).
Each LE includes a 4-input look-up table (LUT), which can implement any
4-input function, a register, and dedicated paths for carry and cascade
chain functions. Because each LE contains a register, a design can be easily
pipelined without consuming more LEs. The specified gate count for
FLEX 6000 devices includes all LUTs and registers.
LEs are combined into groups called logic array blocks (LABs); each LAB
contains 10 LEs. The Altera software automatically places related LEs into
the same LAB, minimizing the number of required interconnects. Each
LAB can implement a medium-sized block of logic, such as a counter or
multiplexer.
Signal interconnections within FLEX 6000 devices—and to and from
device pins—are provided via the routing structure of the FastTrack
Interconnect. The routing structure is a series of fast, continuous row and
column channels that run the entire length and width of the device. Any
LE or pin can feed or be fed by any other LE or pin via the FastTrack
Interconnect. See “FastTrack Interconnect” on
page 17
of this data sheet
for more information.
Each I/O pin is fed by an I/O element (IOE) located at the end of each row
and column of the FastTrack Interconnect. Each IOE contains a
bidirectional I/O buffer. Each IOE is placed next to an LAB, where it can
be driven by the local interconnect of that LAB. This feature allows fast
clock-to-output times of less than 8 ns when a pin is driven by any of the
10 LEs in the adjacent LAB. Also, any LE can drive any pin via the row and
column interconnect. I/O pins can drive the LE registers via the row and
column interconnect, providing setup times as low as 2 ns and hold times
of 0 ns. IOEs provide a variety of features, such as JTAG BST support,
slew-rate control, and tri-state buffers.
Figure 1
shows a block diagram of the FLEX 6000 OptiFLEX architecture.
Each group of ten LEs is combined into an LAB, and the LABs are
arranged into rows and columns. The LABs are interconnected by the
FastTrack Interconnect. IOEs are located at the end of each FastTrack
Interconnect row and column.
